تعريف i., jeol. lös في التركية الإنجليزية القاموس.

loess

any sediment, dominated by silt, of eolian (wind-blown) origin

A homogeneous, fine-grained sediment made up primarily of silt and clay, and deposited over a wide area (probably by wind)

Deposits of silt laid down by aeolian processes over extensive areas of the mid-latitudes during glacial and postglacial times

silt deposited by winds blowing across sparsely vegetated ground during the last Ice Age; mantles many plains, terraces and downs in the eastern South Island and southern North Island

Dust carried by the wind and deposited at the edge of ice sheets and glaciers, and producing a fertile soil, such as the steppes of eastern Europe [Pronounced: low-ess or løss]

Unstratified, geologically recent deposit of silty or loamy material that is usually buff or yellowish brown and is deposited chiefly by the wind. Loess is a sedimentary deposit composed largely of silt-sized grains that are loosely cemented by calcium carbonate. It is usually homogeneous and highly porous and is traversed by vertical capillaries that permit the sediment to fracture and form vertical bluffs

1 )Unconsolidated, wind-deposited silt and dust 2 )An extremely fertile, fine-grained loam composed of quartz, feldspar, hornblende, mica, and clay; deposited by the wind during the Pleistocene Age It originates in arid regions from glacial outwash (Morris 1992)

A buff-colored, wind-blown deposit of fine silt, which is frequently exposed in bluffs with steep faces The thickness can range from 6 to 30 m The loess of the USA and Europe is thought to be the fine materials first transported and deposited by the waters of melting ice sheets during the glacial period It was later blown considerable distances with, in some cases, deposition in lakes The origin of Asiatic loess, however, is apparently wind-blown dust from central Asian deserts (Source: Carbon Dioxide Information Analysis Center, 1990)

A wind blown deposit or parent material Mainly silt Often formed by wind action on dried-up glacial lake beds

A soil made up of small particles that were transported by the wind to their present location

non-stratified sediment composed of silt-sized particles deposited by the wind These windblown dust deposits were derived from glacial materials

Loamy soils deposited by wind, often quite erodible

A clay, consisting of fine rock-flour (mainly quartz) that originates in arid regions and is transported by wind

Earth that is comprised of wind-blown dust that has accumulated to depths of over 3,000 feet Loess is very fertile, but beause it does not hold water, it makes farming very difficult

Fine dirt deposited by wind usually from arid or glaciated areas

Non-stratified silt, clay, and dust, originating as glacial sediment, but re-deposited by wind Wind-blown silt

A quaternary deposit, usually consisting of a fine yellowish earth, on the banks of the Rhine and other large rivers

A deposit of windblown sand and clay weakly cemented by calcite

An unstratified, usually buff to yellowish brown, loamy deposit created by fine mineral particles carried by the wind Pronounced "less "
